One-pot, Facile Synthesis of Quinoxaline Derivatives from Bis-aryl α-Hydroxyketones and o-Arenediamines using KMnO4/CuSO4
Abstract
KMnO4/CuSO4, a readily available reagent combination, was found to be effective for the high-yield synthesis of quinoxaline derivatives from bis-aryl -hydroxyketones and o-arenediamines in hot ethanol.
